Progress on ambient water quality 2021: global indicator 6.3.2 updates and acceleration needs

Target 6.3 is: “By 2030, improve water quality by reducing pollution, eliminating dumping and minimizing release of hazardous chemicals and materials, halving the proportion of untreated wastewater and substantially increasing recycling and safe reuse globally.” Indicator 6.3.2 monitors the proportion of bodies of water with good ambient water quality, as per national and/or subnational water quality standards and based on measurements of five water quality parameters that inform on the most common pressures on water quality at the global level. This report presents the global status on ambient water quality and acceleration needs to achieve target 6.3 by 2030, based on the latest data on indicator 6.3.2.
